Cautions

Pennyroyal is not to be taken internally.

Peppermint should not be given to children under five.

Do not take the essential oil internally. It should not be used for children under twelve.

Very young children should not be given strong tea or rubbed with ointments containing menthol since it could cause them to gag or choke.

Avoid prolonged use of the essential oil as an inhalant.

Mint can irritate mucous membranes and should not be given to children for more than a week without a break and, only then, in diluted doses.

Be caution in taking peppermint if breastfeeding as it can reduce the milk flow.

Pure menthol can be fatal if ingested, and must always be diluted and, even then, may still cause some allergic reactions. Therefore, usage must immediately be stopped if such symptoms as headache, rash, or flushing begin.

Since menthol can stimulate the gallbladder, mint should not be taken if there are gallstones present.

Mint is also contraindicated in those who have a hiatal hernia or heartburn caused by gastroesophageal reflux disease (GERD). Menthol can worsen the disease by relaxing the sphincter between the esophagus and stomach, allowing stomach acids to backwash into the esophagus.

Description

The plant is thought to be indigenous to Europe, northern Africa, and western Asia. It was introduced into America, Australia, and Madiera.

Generally, mint is a strongly aromatic square-stemmed annual that can grow to thirty-two inches and produce serrated leaves which are harvested just before flowering. Various species grow naturally worldwide and can quickly take over a garden by sending up new offshoots from their rapidly spreading roots, in addition to scattering seeds far and wide. The species readily inbreeds so they are sometimes difficult to tell apart, but all have a distinctive minty odor and a fresh taste.

In Mexico, the field mint grows wild along the banks of streams and brooks, as well as being cultivated in gardens. The leaves look like mint; but the small, round purple flowers look more like Pennyroyal, for which it is often mistaken. One type of Pennyroyal (Hedeoma oblongifolia or H. pulegioides), is a distant relation, but Mexicans use them interchangeably. The only difference is in the stem with pennyroyal branching out, while brook mint has only one stem.

Peppermint is a perennial hybrid of Mentha aquatica and M. spicata, forming M. Piperita. The essential oil is obtained from the stem of the plant through distillation.

Peppermint is used to increase the flow of digestive juices and bile while relaxing the muscles of the digestive tract. It reduces colic, cramps, and gas, and helps to soothe the lining and muscles of the colon, relieving spastic episodes.

Applied to the skin, peppermint relieves pain and reduces sensitivity.

Since it reduces nausea, mint is helpful for travel sickness.

Today, peppermint is preferred in the West, while the Chinese prefer to use field mint and have done so for at least a thousand years to treat fevers, flu, colds, nosebleeds, diseases of the nose and throat, snake and insect bites, and nervous disorders in children. In China, the leaves are often added to salads and vegetable dishes.

In New Zealand, mint is used as a tonic and to treat colds, flu, headaches, colic, gas, and nausea. Oil of peppermint is put on burns to relieve the pain and, when taken on a regular basis, dissolves gallstones.

In India, mint is used to tone the stomach, stimulate the mind and body, rid the intestines of gas, and relieve muscle spasms. There, chutney is not just a condiment, but also a way of taking medicinal herbs. Mint is added to fruit chutneys to be taken as a tonic with every meal. The western practice of using mustard and ketchup came from the Indian chutneys, but these certainly do not possess any of the healthful qualities that the Indian chutneys contain.

The Arabs use mint for many ailments, including skin diseases and as a general tonic. They are also one of the few nations who believed that mint was a tonic for the mind as well as the stomach.
